I missed y'all :) Hope everyone is keeping good health!

If I create own symbols (with arrows a.s.o.) in a unicode-font. Is there a convention, on which numbers I should place them?

Faheem Mitha

6:21 AM

@barbarabeeton You don't think the civil rights laws were effective? I don't really know the history, apart from what I have read. Which could be incorrect or incomplete or just misleading.

David Carlisle

7:28 AM

@PauloCereda breakfast

@cis if they are complete characters a annotated with the stroke order you could use the usual slots. if they are partial characters that make up your display then use the private use area: ranges of unicode set aside for private use by non standard encodings

@Thor #1 is always replaced by the supplied argument unexpanded

kauray

I placed a tabular inside a subfigure, is there a way to caption it as Table ... ?

David Carlisle

@kauray \captionof{table}{...} from caption or captionof packages

kauray

7:45 AM

@DavidCarlisle would that work for an individual subfigure?

I mean the entire Figure would have a caption as figure but only a subfigure with a table would have a table subcaption so to say

asking, since it gives an error " Package caption: table inside subfigure."

Ulrike Fischer

@kauray you certainly can force the subcaption type.

kauray

okay will try it out, must have made some other mistake that is leading to the error

@CarLaTeX Thanks for the duck-matrix article! Reads very helpful and in fact, I think I couldn't get it done because I thought I could make use of &[...] in multiple rows and with even different values.

I'll use pure tikz with positioning now :)

Rmano

@Just_A_Man Well, yes, the duck thing is a bit of a tongue-in-cheek thing (your idea about HW for contributors is sound); but on the other hand, I contribute to the LaTeX project because, well, it's fun. That a thing that I also try to transmit about instrumentation to my student; keeping a fun part in serious stuff help maintaining interest. You start drawing bears and then you use the methods you learnt in circuitikz...

cis

Ah, OK. I find out, that I should use `U+E000 .... U+F8FF`

http://www.unicode.org/faq/private_use.html

David Carlisle

9:14 AM

@cis yes although as I say it's probably easier to use them if you encode them in the usual character slots

@kauray the other thing to note is that it will float with the figures so can float out of order of tables.

Ulrike Fischer

@cis you could look at the logix package, that is a font which adds lots of symbols in the private area and makes them accessible for xelatex/lualatex.

Paulo Cereda

ooh weekend

CarLaTeX

10:18 AM

@ComFreek You could do some tricks using empty cells, see this example:

\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
\[
\begin{tikzcd}
a & &[-25pt]b&[-40pt]&&c\\
d&e\\
f&&g&&h
\end{tikzcd}
\]
\end{document}

Thor

12:30 PM

@DavidCarlisle Thank you for your reply. I'll have to post a question then, because when written it is all expanded. I must be messing something else up. :)

ComFreek

How can I star specific sections in a document such that they appear as "3* Section", for example?

I looked into the titlesec package docs, but couldn't find anything.

@CarLaTeX Yeah, not sure if that scales well for big diagrams :-)

David Carlisle

12:47 PM

@Thor sure but it is writing that expands \write is like \edef not the passing of #1 you can \write\@auxout{\unexpanded{#1}} for example.

@ComFreek locally change \def\@seccntformat#1{\csname the#1\endcsname*\quad} ?

@ComFreek but that would just put a * in the heading \ref would still give 3, if you want \ref to return 3* you need to change it elsewhere

@Thor or the classical solution is to use \protected@write

ComFreek

1:19 PM

@DavidCarlisle Would that also change the ToC?

If so, that'd work for me

Ulrike Fischer

@ComFreek \@seccntformat changes only the title. If you want the change everywhere where the number is used, redefine \thesection.

ComFreek

hm, that sounds hairy

Isn't that a common request actually to have section titles numbered?

I've seen it often used for "may be skipped on first read"

Ulrike Fischer

@ComFreek well they are numbered. But it is quite uncommon to add additional symbols on the fly.

ComFreek

*starred, sorry

David Carlisle

@ComFreek should do, yes

ComFreek

1:32 PM

@DavidCarlisle doesn't seem so, it perfectly adds the star to the section title within the document, but not ToC, though.

I am using LNCS as the document class if that makes a difference.

David Carlisle

@ComFreek yes probably easiest to locally change thesection, as ulrike says \protected@def\thesection{*\thesection} fro example

ComFreek

"undefined contorl sequence \protected@def"

I tried it via:

\begingroup
\makeatletter
\protected@def\thesection{*\thesection}
\section{Test}
\makeatother
\endgroup

David Carlisle

protected@edef

Ulrike Fischer

@DavidCarlisle that would give a wrong number wouldn't it? or is arabic robust?

ComFreek

That doesn't work either:

David Carlisle

1:39 PM

@ComFreek ignore me, just do whatever @UlrikeFischer says (and blame her if it doesn't work, or even if it does)

ComFreek

wait, it does, but indeed gives the previous section number

and it doesn't appear when using \ref

Ulrike Fischer

@ComFreek do it like this

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{etoolbox}
\begin{document}
\tableofcontents
\section{A}

\ref{blub}
\let\orithesection\thesection
\appto\thesection{*}
\section{B}\label{blub}
blub

\let\thesection\orithesection

\section{C}
\end{document}

ComFreek

wonderful!

\newcommand{\starredSection}[1]{
	\let\orithesection\thesection
	\appto\thesection{*}
	\section{#1}
	\let\thesection\orithesection
}

I wonder whether there should be a canonical Q&A for this

Ulrike Fischer

@ComFreek good blaming ;-)

David Carlisle

@ComFreek add some % at ends of lines or egreg will be upset

@UlrikeFischer testing code will get you nowhere

Ulrike Fischer

2:13 PM

@DavidCarlisle I got Bruno to extend his code ;-)

Just_A_Man

@Rmano That's where we differ. To me, using (La)TeX is simply part of my job. I see nothing funny in bears, ducks, or squirrels. Two decades ago, I was into IOCCC; that's when I would have probably found LaTeX funny, too. Now, these times are inevitably gone.

@Rmano *that's when I would have probably found LaTeX funny -> that's when I would have probably found LaTeX fun

ComFreek

3:34 PM

This is a align* environment. How can I make an arrow "|->" from left to right spanning over both rows?

David Carlisle

3:55 PM

@ComFreek you mean like this?

Sebastiano

5:27 PM

@egreg Very kind egreg with such kindness when you have a little time could you take a look at this question? math.stackexchange.com/questions/3734680/…. Thank you very much.

barbara beeton

6:15 PM

@FaheemMitha -- The laws didn't cover everything. They didn't change people's minds. And simmering injustices have been fanned into active flames by certain high-ranking individuals who are unqualified for their positions, but who are effective rabble-rousers and snake-oil salesmen. Maybe a clear majority of voters will come to their senses; I hope so.

Faheem Mitha

@barbarabeeton Well, like they say, the past is alive in the present. And the USA has a very ugly past.

ComFreek

7:13 PM

@DavidCarlisle Yes, perhaps the left vertical bar not that high, but yes

it suffices if it's just a thick |-> between the first and the second row pointing from left to right

I have no idea on how to do this. In tikz I'd just draw it, fine, but here, it seems not so easy

please do not waste your time on this, though, I do not plan to touch these slides again anyway before the talk. Already put way too much time in them

Rmano

@ComFreek You can use tikzmark to mark some point in the equations and then just draw it in overlay mode...

ComFreek

that sounds like a clean approach

David Carlisle

7:39 PM

@ComFreek probably easiest to do it in tikz, just use tikzmark or similar to find the coordinates of the alignment then draw an arrow.

oh @Rmano said that already:-)

Ulrike Fischer

@DavidCarlisle it is quite fast, even if one considers that it runs only once.

David Carlisle

@UlrikeFischer yes I should finish up the coding so it has more cases. definitely faster than my machine, even though it's the smallest machine amazon offer (and free:-) not sure how it would cope with multiple simultaneous access but same is true of all of these servers.

cis

@DavidCarlisle @UlrikeFischer Well, the question of where I should put my own characters in Unicode is primarily order fanaticism of mine. In itself it doesn't matter anyway, because my characters will form their own font anyway.

Otherwise U + E000 ... U + F8FF is a nice area. However, supplies
`\foreach \n in {57344, ..., 63743}`
too big dimensions....

One can certainly fix it, but right now I don't have the nerve to deal with such minor matters.

It is a fundamental question anyway, why someone creates such a professional package (TikZ), knowing well that it can be completely slo…

David Carlisle

@UlrikeFischer also it's using pdf.js which (I would think) ought to be slower than using the built in renderer, at least the first time when you have to get pdf.js

@yo' should be worried though that he has serious competition.

Ulrike Fischer

@DavidCarlisle I didn't see a delay, but perhaps I had it in the cache from previous tests. And the error message is in a nice red box ;-)

David Carlisle

7:49 PM

error? I never see errors as i never have bugs

Ulrike Fischer

@DavidCarlisle you could try with \tehsection.

cis

8:15 PM

@Skillmonlikestopanswers.xyz

cis

8:32 PM

@Skillmonlikestopanswers.xyz That looks fine. You could consider adding a function showstrokeorder = true to quak.sty.

manooooh

8:53 PM

@samcarter_is_at_topanswers.xyz thanks! So you added \only<6-> to the code. That's a good approach, however, in my real document it does not do a effect. Probably I am doing something wrong, because the extra space is still there... :/

David Carlisle

Blame @UlrikeFischer?

Q: \footenote color is changed, and without hyperlinking

I have my bibliography / sections labeled for hyperreferencing and all of that.... and everywhere else there is \footnote[#]{reference} When I make the pdf here is what I get: The pdf has the exact small, raised footnote markers that I want but they are all blue and without hyperlinking to the bi...

hyperref

Ulrike Fischer

@DavidCarlisle I saw it but found it a bit difficult to understand -- at least at this rather late hour ;-)

Oh you commented in this sense.

David Carlisle

@UlrikeFischer yes I blamed you from the title. When I read the question I didn't understand it at all I left a comment

Ulrike Fischer

9:08 PM

@DavidCarlisle but basically links to footnotes are complicated and even with complete examples not easy to debug.

David Carlisle

@UlrikeFischer yes.

Nov 11 '17 at 9:50, by David Carlisle

Don't use footnotes in your books, Don.
\author JILL ^{KNUTH} (1962)

Ulrike Fischer

@DavidCarlisle but I'm not sure if the question if about links to footnote, or about links from some content of the footnote to somewhere else.

@DavidCarlisle I'm just preparing the pdftexcmds for upload. Should we remove the tds-zip? It looks a bit odd for three files.

David Carlisle

@UlrikeFischer yes good plan

Ulrike Fischer

@DavidCarlisle ok (actually there are four files when it is unpacked, I forgot the lua, but it isn't much nevertheless).

@DavidCarlisle looking at the structure, the lua should probably move into the tex folder (currently it is in script).

David Carlisle

9:30 PM

@UlrikeFischer I suspect that it being in script is why I kept the tds.zip, I didn't spend long thinking about each split but I dropped the tds if I noticed that everything was under latex/macros

Ulrike Fischer

@DavidCarlisle it seems to work fine in tex/latex beside the sty (if one puts the original in script out of the way). I think I will add a note to the upload that we suggest to move it.

@DavidCarlisle l3build tag didn't tag the readme ;-(.

David Carlisle

@UlrikeFischer originally it was not only in scripts but had the weird duplicated copy oberdiek.pdfcmds.lua I never did work out what they were really for, or whether they were needed at all since luatex used kpse for loading lua modules

@UlrikeFischer I should update all the tag functions... (there are a lot of them...)

Ulrike Fischer

@DavidCarlisle I don't understand what is missing. The pattern looks ok.

Ah probably tagfiles is missing. I think I will risk a try ...

@DavidCarlisle now it worked.

samcarter_is_at_topanswers.xyz

9:54 PM

@manooooh Yeah, instead of wrapping the item into \only<6->{}, you could also use \item<only@6> The final. Of course I don't know your real document, so no idea what might be the problem there

Ulrike Fischer

10:10 PM

@DavidCarlisle this is a can of worms. Now that I looked at it: the dtx actually says to install the style in tex/generic ;-(. Should we change this to tex/latex (where it is now)? And it mentions the tds.zip, so I should better adapt the text.

David Carlisle

@UlrikeFischer isn't it supposed to work with plain? in which case generic makes sense

Ulrike Fischer

@DavidCarlisle yes. OK I will tell ctan that both files should go into tex/generic and adapt the docu accordingly. How do one have to adapt build.lua to install in tex/generic?

David Carlisle

@UlrikeFischer oh if it all goes in generic there's a top level l3build variable for tds root but otherwise if its a mixture tdslocations but it's not setting either at the moment, oh I see we put it under latex last time:(

@UlrikeFischer easiest is like etexcmds/build.lua:

tdslocations={
"doc/latex/etexcmds/etexcmds.pdf",
"source/latex/etexcmds/etexcmds.dtx",
"tex/generic/etexcmds/etexcmds.sty",
}

@UlrikeFischer or don't bother with tdslocations but set tdsroot = "generic" so it all goes there.

Ulrike Fischer

@DavidCarlisle yes just did this.

David Carlisle

@UlrikeFischer thanks

@UlrikeFischer how did we end up with so many repos:-)

@DavidCarlisle well I made the error to accept some invitations ;-) And I lend you a sword

@DavidCarlisle uploaded.

David Carlisle

@UlrikeFischer you may go to bed happy:-)

Ulrike Fischer

@DavidCarlisle ;-).

@DavidCarlisle how to you pull all the repos in one? did you write a script or does some magic exist here?

David Carlisle

10:47 PM

the ho-pull script is below (I have similar ones for status and commit (if I'm feeling brave:-)

for i in */.git
do
# pull
(cd ${i%.*}; echo -e "### ${i%.*}"; git pull --rebase  )
done

Ulrike Fischer

11:12 PM

@DavidCarlisle I should write me such a script too.

David Carlisle

11:25 PM

@UlrikeFischer the same script updates all the latex3 repos as well so long as you arrange the local directory structure to group things
